Thanks. All three versions produce output similar to

# rpm -e --test $(locate libavformat56)
error: package /usr/share/licenses/libavformat56 is not installed
error: package /usr/share/licenses/libavformat56/COPYING.GPLv2 is not installed
error: package /usr/share/licenses/libavformat56/LICENSE.md is not installed

I'm not sure what that means (never used locate before and don't know
much about rpm.
